JESSE S. WENTWORTH, OF NORWOOD, OHIO, ASSIGNOR TO THE HEIEKIN CAN COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO.

CAN.

T all 'whom t may concern:

Beit known that I, JESSE S. WENTWORTH, a citizen of the United States of America, and resident of Norwood, in the county of Hamilton and State yof Ohio, have invented new Improvements in Cans, of which the embodying following is a specification.

The object of my invention is to provide a stable and non-leakable can, which may be used 'as a substitute for the ordinary tin can, and in which a sheet metal is used, which is much thinner and less expensive' than the metal used in' tin cans.

In the accompanying drawings, in which I have illustrated the preferred embodiment of my invention,

AFi re 1 is a lan view of a strip of materia s, which, w en rolled, will form a can body embodying my invention.

Fig. 2 is a central sectional view of a can my invention. Fig. 3 1s a similar view of a modified form of my invention.

Fi 4is a sectional view, taken upon line 4-4 of Fig. 2, of a part of a can body embodying my invention.

' Fig. 5 is a sectional view of a part of a can body, taken upon line 5-5 of Fig. 3.

Heretofore in the manufacture of tin cans, the sheet metal used has been of a gage such that it has suiicient stability of itself to form the body of the can, and when, with the sheet metal, paper has been used, the latter has een simply a covering for the former. ereas, in my can, I use a sheet of metal, which is of so small a gage,

- that it has not suflicient stability alone to form a body for the can, and I lmpart the necessary stability by combining with this mutable sheet metal, paper or other sheetv material.

The sheeti of metal which I use may be a ine wire screen, a thin perforated sheet metal, or a sheet metal of small or paperlike gage, and indented at intervals.' v

' The sheet material which gives stability to my sheet of metal can,Y consists preferabl in the body of the y of `a heavy fiber-Y paper, rwith unfinished surfaces, such as wra ping paper.

T e can may be lined interiorly and covered exteriorly with awoven paper, such,v as

plated label paper, or, instead of such lining and covering, I may use a lining or covering of lacquer, such, as forinstance. a cobalt Specication of Letters Patent.

lacquer which, when baked to 30() degrees Fahrenheit, hardens.

. Instead of this liber-paper, I may use sheets of metal foil, such as tin foil or aluminium foil, to give stability to the sheet metal. v l f In the manufacture of my can, I prefer to roll up a strip of the materials into a cylindrical shape, to form the body of the can, first alinin the sections of materials, in the order whic they are to occupy in the can body. IFor instance in Fig. 1, I have illustrated the order of arrangement Where the can body is to have a lining 1 and a covering 2 of Woven paper. Between sections 1 and 2, there is secured a section 3 of fiber paper. The ends of the sections are cut preferably at acuteand obtuse angles to the edges thereof, so as to make an angular joint thereof in the can body. Instead of these angular cuts at the ends, I may use an irregular cut, so as to avoid a right angle joint.

'Section 1 is made of a length, such that its ends will overlap when the strip is rolled, and will form the lining of the can body. Section 3 is made preferably of a length, such that it will be rolled upon itself several times, when the strip is rolled. Section 2 is made of a len th, such that its ends will overlap, and it w1ll form the covering of the can body.

Asheet metal sectionl 4 is placed upon the inner surface of section 3, at a distance from section 1f, such that the part of section 3, between the end of section 4 and section 1,*will be equal to the periphery of the can. Section 4 is of a length such, that when rolled, its ends will overlap. To hold section 4 in place upon section 3, I may form pockets 5 and 6 for the corners thereof, by pasting pieces of paper-to strip 3 over said corners. v

Before the strip of material is rolled, I preferably apply to the inner surface thereof a layer of glue.

In instances where a lacquer finish -is used in place of the woven pager lining l and cover 2, the lacquer may e applied either before or after the strip has been rolled. This lacquer finish is especially advantageous for use upon cans,l which are intended for holding acids. In some instances, I prefer to use the lacquer only upon that part of the strip which is to form the inside of the can. My can is one which is adapted to take vrious kinds of finish, as for instance, instead of the lacquer finish, l may place un oil finish upon the inside of the can, und a dipped finish upon the eXteror thereof.

While I prefer to place the strips of ma,- teriul in alinement with each other, and then to roll the strip upon cylindrical forms, to form the can body, l may roll the sheet metal, es for instance, the Wire mesh, into aA cylindrical form, und then dip it in bulk pulp and then compress the pulp firmly into und on the outside of the cylindrical Wire mesh.

The bottom of the can may be formed either of u disk 7, made of layers of sheet metal end paper, such as illustrated and described in connection with Figs. l and 5, or muy be made of a.` disk of sheet tin 8. In Fig. 2, the disk 7' is shown as being secured to the can body by having its downturned end 9 rolled into the up-turned end l() of the can body. ln Fig. 3, the bottom 8 is remore secured by up-turningy its iange 1l around the lower end of the cylindrical body.

open end of the can body may be finished by securing thereto the usual flanged end 12,

which cooperates with the tapered top 13.

l/Vhet l claim is:

l.' A can, the body of which comprises o, cylinder of mutable metal, layers of fibrous paper covering the metal, and a lining and :i cover for the fibrous peper.

2. A can, the body of which comprises a cylinder of mutable metal, layers of fibrous paper covering the metal, and a liningend a cover of' Woven paper for the fibrous peper.

ln testimony whereof, l: have hereunto subscribed my nume this 24th dey of August, 1917.-
